Products Description
Copper Alloy Foil Sheet are commonly made of molybdenum Copper or tungsten copper material which is made of powder metallurgy and rolling process, with high electrical conductivity, easy processing, high thermal conductivity, corrosion resistance, high temperature resistance, high plasticity, good welding performance, high surface finish, long service life and other excellent characteristics.
As a composite of tungsten and copper. It combines the properties of both metals, resulting in a mixture material that is heat-resistant, wear-resistant, highly thermally and electrically conductive, and easy to machine. Tungsten copper are widely used in mechanical, electrical, electronics, metallurgy, aerospace and other industries as being electrical vacuum contact materials, EDM and ERW electrodes, electronic packaging materials, as well as precise components used in rockets, missiles and other special-purpose.
Features of our tungsten copper
Tailor-made composition and properties such as CTE
Homogenous structure, excellent performance
High precision
Good machinability and mechanical strength
The copper alloy foil sheet possesses exceptional thermal conductivity and electrical conductivity which enable it to efficiently transmit electricity and heat. Its sheet form bestows a good degree of flexibility. Such adaptability ensures ease during processing, molding, and even intricate complex structural requirements.Copper alloy foil sheet has some degree of corrosion and wear resistance which allows it to perform stably in a diverse range of environments. In some cases, the copper alloy foil may also have special properties like profound elasticity and fatigue resistance depending on the alloy composition.

applications of Copper Alloy Foil Sheet
Copper alloy foil sheet is employed in the electronics industry to manufacture components like circuit boards and electro-magnetic shields designed for modern compact and lightweight electronics. In automotive engineering, it is used to manufacture sensors, connectors and other parts of electronic systems to improve their functionality and dependability within the automotive systems. It is utilized in aerospace to reduce the total weight of the aircraft by fabricating skeletal and electronic structures which are lightweight. In addition, copper alloy foil is applied to make conductive components and sensors in medical appliances to provides accurate operations of the devices.
